Disable SIP ALG on BT Business Hub 3

SIP ALG is controlled per device attached to the router, it’s not a setting for the router as a whole.

  1. Log into your router
  2. Navigate to: Settings>Advanced Settings>Business Network>Devices
  3. Select a device by clicking on it
  4. Change ‘Disable SIP ALG’ to ‘Yes’
  5. Hit ‘Apply’

This applies to the BT Business Hub 3 (BH3) and possibly also the Home Hub 3 (HH3).
